Ensuring safe and effective radiotherapy treatment
Radiotherapy, also known as radiation therapy, is commonly used to try to cure someone’s cancer, prevent it from coming back, or help relieve symptoms.
Most radiotherapy is administered by a machine that directs high-energy rays to the cancer, but sometimes it’s delivered by tiny radioactive pellets placed inside the body.
As technology advances, radiotherapy is becoming more complex. Regular review of treatment standards is needed to ensure patients have access to the right radiotherapy for their situation. Given rapid technological evolution, it’s also important that cancer centres regularly assess the quality of their radiotherapy programs, report and learn from any rare incidents, and are continuously working to maintain a good standard of care.
Together with its members and initiative partners, CAPCA is helping Canada to remain at the forefront of radiotherapy planning and delivery through driving practice harmonization, improving quality and patient safety, and supporting equitable access to care.
This work is led by the Canadian Partnership for Quality Radiotherapy (CPQR) as a standing committee of CAPCA. CPQR reflects a unique collaboration between radiation oncologists, medical physicists, radiation therapists, and oncology nurses along with their respective professional associations, individuals with lived experience, and other health system organizations.

Who’s involved
- Several professional organizations participate in CPQR and are involved in the implementation of radiotherapy quality and safety initiatives:
- Participation in CPQR includes provincial cancer agency and program radiotherapy experts, such as radiation oncologists, medical physicists, radiation therapists, radiation oncology nurses, and patient and family advisors with lived experience
- The Canadian Institute for Health Information partners with CPQR on the National System of Incident Reporting – Radiation Treatment (NSIR-RT), a tool for cancer centres to report, track and analyze safety incidents to drive accountability and continued improvement in radiotherapy quality.
- Accreditation Canada collaborates with CPQR to ensure cancer care standards reflect current radiation treatment practice and quality improvement.
- Operational costs of CPQR are financially supported in part by the Canadian Partnership Against Cancer.
Radiotherapy Resources and Partnerships
In addition to our efforts, CPQR’s resources and partnerships with other groups emphasize high-quality, effective radiotherapy.
